maaien,

. Illinois, have invented anew' and useful' 111-' ternalfombustion'? Engine Equipment', of .which the, following is a. specication.

"My invention relates to improvement in providing for causing the explosive charges ,introduced into the engine vfor ring thereinLto contain a desirable amount of waterlvapor, 'thereby'` to produce highly eiiicient and economical' operation of the engine; and

lefniy ,objectfis yto provide at novel and' simple apparatus ci this character, which may be used vunder Widely ldide'ring conditions pre- Isented by ergine structures lof di'erent types.- y v Reterrmgto the accompanying drawing:j

i 4.Figure 1 is a view in' elevation, partly diagrmnniatic, oi` an internalcombustion enfog, supplying damp air to the carburetor;

gini,- With acarbureter therefor as commonly; used on automobiles, and means, constructed in accordance with. my invention,

Figi?" 2 is an enlarged 'section taken at the I line 2 'on Fig. 1 and viewed. inthe direction ofthe arrow; and Fig. ,3, a section taken at the line hon Fig. 1 and viewed in" the direction ofthe arrow.

, 'ln-1 Fig.4 1, I have shown my. invention as applied to internal combustion engine equip# nent as used on automobiles, in-Whiclrfi is the engine, 5 the inlet-pipe'for lconducting explosive charges from the carbureterl 6 lnto the cylindersotthe engine, and 7, the ez;-

. haust pipe. Thelcarbureter shown may be of any .suitable construction as commonly used. In the drawings, the gasolene-inlet for thev carburetor is represented at 8,' and the air-inlet at 10, the carbureter shoWnhaV- ing a single air-inlet, though the 'invention may be. used with a plural a1r-mlet c arburetor. The air-inlet 10 opens into a pipe '1'1 which communicates With the-lower end ot a pipel extending at its upper end into a tank 13'f0r Water, provided with a capped Waterfl'ling opening' 13a.v The tank 13 also' contains a-pipe le which extends at its up-l -per end into 'saidtank and at its lower,`open,

end through thefbottom of the tank, this pipe, 4being provided for conductingair into the tank above the' Water level ,15 therein'. The

tank 13 is provided for mixing Water-vapor- With the air-supplied to 1t through the plpe V Specication o1' Letters Patent. 'y Patemgdl Die@ 14, 1935, applieationnledune 7, 1915; y frlerall No. 332,551. I

14:, by the suction action'of the engine, the

Water in the tank 13 being heated in any desirable way. 1n the -construction illus-Y trated, l avail myself of the waste-heat generated by the engine, for heating the Water in the tank, and this is accomplished in the preferred'WayLby providing a coil 16 of pipe about the exhaust-pipel 7 of theengine and connecting the ends of this coil with the interior of the tank 13 in any way suitable to obtain a circulation of the Water -thereinwthis being leffected in the construction illustrated by attaching one end ofthe coil 16 at a higher-point on the tank than the other. The heat from the exhaust-pipe causesthe water in the tank 13 to become vaporized, the Vapor mixing with the air supplied tothe tankl through the pipe 14 and thus charging it with moisture before entering the carburetor. By preference the airbefore enteringvthe tank 13 by Way of thepip'e 14 is heated, and as a fconifenient Way of. doing this, I utilize the heat from the exhaust gases, l preferably employing a eol funnehshape'd inlet "17. for the pipe 14 which lies closely adjacent to the caltanet pipe'in partially overlapping relation, but

outV of Contact therewith, as shown. tank 13 preferably `is provided Withmeans 'for preventing the Water therein 'from splashinginto the upper open ends of the pipes l2 and 14, the crm of means lshown comprising radially disposed plates.18confined in the tank 13 in accordance with corn-f .mon practice.

it will readily be -understood from Athe foregoing that Water-vapor inl approxi- That mately :uniiorm quantities is mixed with the-I air and gasolenerto form the.V charges t0-'be fired in the cylinders of the engine, and that by my invention the `advantages resulting@ from the mixture lof water-vapor Witlithe air and gasolene, or the like, may be availed' ico los

What l claim as new and desire to secure by Letters Patent isze 1. The'combination with an internal `combustion engine, of a tanlgjfor water containing an air inlet, a pipe-coll arranged toibo heated by the exhaust pipe of theriengine and Connected at its ends with said ank, a

conduit (mening into said tank above the water therein, and in eonnnunication with the eyiinders of the engine, and means for mixing` Kg'afsoienm or the like5 with the air and` vapor pa sing' through saideonduit.

The eonil'iination with un internai coinbustion engineflof a tank for,,waterljeontaining' an air in1et a pipeveoil fllglaligd t0 be heated hy the exhaust pipe offt'heeneine and Connected at its ends at different eievations with said tank, a conduit opening into Shid tank above the water thereinandhin communication with the cylinders of the engine, and menne for' mixing; gasolene, or the like,l with thehir and vapor passing" through said-conduit.

3. The combination with an internal coinhustion engine, of a tank `for Watenmeans yfor heating the Later in said tank, pipes eX- tending upwardly through said tank with their upper ends above the water-level therein, one of saidpipes et its other end being in connnunication' with the carburetor of the engine and the either of said pipes at its other end in communication with the atmos phere and arranged to cause air passing therethrough to be heated by the exhaust from the engine, and'means for. mixing gasoiene, or the like7 with the air and` vapoi"
